I've had requests for paper canopies that would fit microquads like the ladybird and the WLToys V939. Although I do not own one, i've been helped gathering all the needed measures to make educated guesses on the size and shape of these things. They might work with just some or all of them... guess you'll have to experiment and see if they work with your quad, and eventually adapt the boom holes to your need (i have provided references thou). Enjoy!
